GENERAL HAZARDS

Any AC generator that is used for backup power if a NORMAL (UTILITY) power source failure occurs, must be isolated from the NORMAL (UTILITY) power source by means of an approved transfer switch. Failure to properly isolate the NORMAL and STANDBY power sources from each other may result in injury or death to electric utility workers, due to backfeed of electrical energy.

Improper or unauthorized installation, operation, service or repair of the equipment is extremely dangerous and may result in death, serious personal injury, or damage to equipment and/or personal property.

Extremely high and dangerous power voltages are present inside an installed transfer switch. Any contact with high voltage terminals, contacts or wires will result in extremely hazardous, and possibly LETHAL, electric shock. DO NOT WORK ON THE TRANSFER SWITCH UNTIL ALL POWER VOLTAGE SUPPLIES TO THE SWITCH HAVE BEEN POSITIVELY TURNED OFF.

Competent, qualified personnel should install, operate and service this equipment. Adhere strictly to local, state and national electrical and building codes. When using this equipment, comply with regulations the National Electrical Code (NEC), CSA Standard; C22.1 Canadian Electric Code and Occupational Safety and Health Administration (OSHA) have established.

Never handle any kind of electrical device while standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT.

Table of Contents

Because jewelry conducts electricity, wearing it may cause dangerous electrical shock. Remove all jewelry (such as rings, watches, bracelets, etc.) before working on this equipment.

If work must be done on this equipment while standing on metal or concrete, place insulative mats over a dry wood platform. Work on this equipment only while standing on such insulative mats.

Never work on this equipment while physically or mentally fatigued.

Keep the transfer switch enclosure door closed and bolted at all times. Only qualified personnel should be permitted access to the switch interior.

In case of an accident caused by electric shock, immediately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor but AVOID DIRECT CONTACT WITH THE VICTIM. Use a nonconducting implement, such as a rope or board, to free the victim from the live conductor. If the victim is unconscious, apply first aid and get immediate medical help.

When an automatic transfer switch is installed for a standby generator set, the generator engine may crank and start at any time without warning. To avoid possible injury that might be caused by such sudden start-ups,the system’s automatic start circuit must be disabled before working on or around the generator or transfer switch. Turn the generator’s AUTO/OFF/MANUAL switch to OFF. Turn the generator’s main circuit breaker OFF. Then place a “DO NOT OPERATE” tag on the transfer switch and on the generator. Remove the Negative (Neg) or

(–)battery cable.

Section 1 — General Information

RTS “W” Type Transfer Switch

1.1INTRODUCTION

This manual has been prepared especially for the purpose of familiarizing personnel with the design, application, installation, operation and servicing of the applicable equipment. Read the manual carefully and comply with all instructions. This will help to prevent accidents or damage to equipment that might otherwise be caused by carelessness, incorrect application, or improper procedures.

Every effort has been expended to make sure that the contents of this manual are both accurate and current. The manufacturer reserves the right to change, alter or otherwise improve the product at any time without prior notice.

1.2EQUIPMENT DESCRIPTION

The automatic transfer switch is used for transferring critical electrical loads from a UTILITY (NORMAL) power source to an EMERGENCY (GNERATOR) power source.

The transfer switch prevents electrical feedback between the UTILITY and EMERGENCY sources. For that reason, electrical codes require a transfer switch in all standby electric system installations.

When the transfer switch is connected to the engine generator control panel, the control panel constantly monitors the UTILITY voltage and controls the operation of the transfer switch.

1.3TRANSFER SWITCH DATA LABEL

A DATA LABEL is permanently affixed to the transfer switch enclosure. Use this transfer switch only with the specific limits shown on the DATA LABEL and on other decals and labels that may be affixed to the switch. This will prevent damage to equipment and property.

When requesting information or ordering parts for this equipment, make sure to include all information from the DATA LABEL.

Record the Model and Serial numbers in the space provided below for future reference.

MODEL #

SERIAL #

1.4TRANSFER SWITCH ENCLOSURE

The standard switch enclosure is a National Electrical Manufacturer’s Association (NEMA) and UL 3R type. UL and NEMA 3R type enclosures primarily provide a degree of protection against falling rain and sleet; undamaged by the formation of ice on the enclosure.

Should the UTILITY voltage drop below a preset value, and remain at this low voltage for a preset amount of time, the generator cranks and starts. After the generator starts, the transfer switch transfers the load circuits to the generator, the generator then supplies the loads. When UTILITY returns above a preset level the load is transferred back to the UTILITY and the generator shuts down.

1.5SAFE USE OF TRANSFER SWITCH

Before installing, operating or servicing this equipment, read the SAFETY RULES (inside front cover) carefully. Comply strictly with all SAFETY RULES to prevent accidents and/or damage to the equipment. The manufacturer recommends a copy of the SAFETY RULES are made and posted near the transfer switch. Also, be sure to read all instructions and information found on tags, labels and decals affixed to the equipment.

Two publications that outline the safe use of transfer switches are the following:

NFPA 70; National Electrical Code

UL 1008, STANDARD FOR SAFETY-AUTOMATICTRANSFER SWITCHES

NOTE:

It is essential to use the latest version of any standard to ensure correct and current information.

Section 2 — Installation

RTS “W” Type Transfer Switch

2.1INTRODUCTION TO INSTALLATION

This equipment has been wired and tested at the factory. Installing the switch includes the following procedures:

Mounting the enclosure.

Connecting utility and generator power source leads.

Connecting the load leads.

Connecting any auxiliary contact (if needed)

Installing/connecting any options and accessories.

Testing functions.

2.2UNPACKING

Carefully unpack the transfer switch. Inspect closely for any damage that might have occurred during shipment. The purchaser must file with the carrier any claims for loss or damage incurred while in transit.

Check that all packing material is completely removed from the switch prior to installation.

2.3MOUNTING

Mounting dimensions for the transfer switch enclosure are in this manual. Enclosures are typically wallmounted. See the “Mounting Dimensions” drawing.

Handle transfer switches carefully when installing. Do not drop the switch. Protect the switch against impact at all times, and against construction grit and metal chips. Never install a transfer switch that has been damaged.

Install the transfer switch as close as possible to the electrical loads that are to be connected to it. Mount the switch vertically to a rigid supporting structure. To prevent switch distortion, level all mounting points. If necessary, use washers behind mounting holes to level the unit.

2.4CONNECTING POWER SOURCE AND LOAD LINES

DANGER

Make sure to turn OFF both the UTILITY (Normal) and EMERGENCY (Standby generator) power supplies before trying to connect power source and load lines to the transfer switch.

Supply voltages are extremely high and dangerous. Contact with such high voltage power supply lines causes extremely hazardous, possibly lethal, electrical shock.

Wiring diagrams and electrical schematics are provided in this manual. Power source and load connections are made at the transfer mechanism, inside the switch enclosure.

2.4.1 2-POLEMECHANISM

These switches (Figure 2.1) are used with a single phase system, when the single phase NEUTRAL line is to be connected to a Neutral Lug and is not to be switched.

Figure 2.1 — Typical 2-PoleTransfer Mechanism

(400 Amp Shown)

Solderless, screw-typeterminal lugs are standard.

The conductor size range is as follows:

 

Switch Rating

Wire Range

 

 

400A

(1) #4-600MCM or

 

 

 

(2) 1/0-250MCM

 

 

 

 

 

Conductor sizes must be adequate to handle the maximum current to which they will be subjected; based on the 75°C column of tables, charts, etc. used to size conductors. The installation must comply fully with all applicable codes, standards and regulations.

Before connecting wiring cables to terminals, remove any surface oxides from the cable ends with a wire brush. All power cables should enter the switch next to transfer mechanism terminals. If ALUMINUM conductors are used, apply corrosion inhibitor to conductors. Tighten terminal lugs to the torque values as noted on the decal located on the inside of the door. After tightening terminal lugs, carefully wipe away any excess corrosion inhibitor.

All power cables should enter the switch next to the transfer mechanism terminals.

Section 3 — Operation

RTS “W” Type Transfer Switch

NOTE:

Use a torque wrench to tighten the conductors, being sure not to overtighten, or damage to the switch base could occur. If undertightened, a loose connection would result, causing excess heat which could damage the switch base.

Connect power source load conductors to clearly marked transfer mechanism terminal lugs as follows

1.Connect UTILITY (NORMAL) power source cables to switch terminals N1, N2, (N3).

2.Connect EMERGENCY (STANDBY) source power cables to transfer switch terminals E1, E2, (E3).

3.Connect customer LOAD leads to switch terminals T1, T2, (T3).

4.Connect neutral conductors of UTILITY, EMERGENCY and customer LOAD to the neutral block.

Conductors must be properly supported, of approved insulative qualities, protected by approved conduit, and of the correct wire gauge size in accordance with applicable codes.

Be sure to maintain proper electrical clearance between live metal parts and grounded metal. Allow at least 1/2 inch for 100-400amp circuits.

Auxiliary Contacts are rated 10 amps at 125 or 250 volts AC. DO NOT EXCEED THE RATED VOLTAGE AND CURRENT OF THE CONTACTS.

3.3VOLTAGE CHECKS

3.3.1 UTILITY VOLTAGE CHECKS

1.Turn ON the UTILITY power supply to the transfer switch with whatever means provided (such as the UTILITY maim line circuit breaker).

DANGER

PROCEED WITH CAUTION. THE TRANSFER SWITCH IS NOW ELECTRICALLY HOT. CONTACT WITH LIVE TERMINALS RESULTS IN EXTREMELY HAZARDOUS AND POSSIBLY FATAL ELECTRICAL SHOCK.

2.With an accurate AC voltmeter, check for correct voltage.

Single-phaseutility supply:

Measure across ATS terminal lugs N1 and N2; N1 to NEUTRAL and N2 to NEUTRAL.

DANGER

FAILURE TO TURN OFF THE UTILITY SUPPLY BEFORE WORKING ON THE UTILITY CONNECTIONS OF THE ATS WILL RESULT IN EXTREMELY DANGEROUS AND POSSIBLY FATAL ELECTRICAL SHOCK.

5.When certain that UTILITY supply voltage is correct and compatible with transfer switch ratings, turn OFF the UTILITY supply to the transfer switch.

3.3.2 GENERATOR VOLTAGE CHECKS

1.On the generator panel, set the AUTO/OFF/ MANUAL switch to MANUAL position. The generator should crank and start.

2.Let the generator stabilize and warm up at noload for at least five minutes.

3.Set the generator's main circuit breaker (CB1) to its ON or CLOSED position.

DANGER

PROCEED WITH CAUTION. GENERATOR OUTPUT VOLTAGE IS NOW BEING DELIVERED TO TRANSFER SWITCH TERMINALS. CONTACT WITH LIVE TERMINALS RESULTS IN EXTREMELY DANGEROUS AND POSSIBLY FATAL ELECTRICAL SHOCK.

4.With an accurate AC voltmeter and frequency meter, check the no-load,voltage and frequency.

Single-phasegenerator supply:

Measure across ATS terminal lugs E1 to E2; E1 to NEUTRAL and E2 to NEUTRAL.

a.Frequency ....................................... 60-62Hz

b.Terminals E1 to E2 ........................ 240-246VAC

c.Terminals E1 to NEUTRAL............. 120-123VAC
